As Ressy and Valar explained, registration was open the other day alongside the patch release out of celebration for the patch being released. However, you can still catch registration open every 6 hours!
We also have the adblocker disabled because we need ads to fund the server and website. Otherwise, the came cannot run. ^^ If you are upset by this, you can always disable your ads for this site alone, so that way it won't bug you every time you sign into Feral Heart. Hope that helps!
